Abstract

A method for making a photoconductor for electrophotography can comprise depositing a charge generating layer on an electrode; depositing a charge transfer layer on the charge generating layer, where a plurality of charge transfer molecules are disposed within the charge transfer layer; depositing a film of non-conducting material onto the surface of the charge-transfer layer; heating the film and the surface to cause a subset of the charge transfer molecules to move into the non-conducting material, creating in the film a conducting sub-layer and an insulating sub-layer, where the insulating sub-layer is substantially free of charge transfer molecules.
